HEDDLE-FRAM E.

SPECIFICATION forming part of Letters Patent No. 704,455, dated July 8,1902.

Application filed November 2, 1901. Serial No. 80,920. (No model.)

To all whom, it may concern:

Be it known that I, TOUSSAINT J. FUYAT, a citizen of the United States,residing at Hudson, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inHeddle-Frames; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in heddle-frames and the specificmeans employed for locking the heddle-bars in position. Heretoforeframes of this class have been constructed of upper and lower woodenbars connected at their ends by thin metallie, in many cases adjustable,strips, while in others various stiffening means have been resorted toto increase the efficiency of the frame; but in all these constructionsthat I am aware of decidedly objectionable features are prevalent,notably unnecessary weight, which causes undue friction when the framesare operated and weakness of the ends. Also various devices have beendevised for locking the heddle-bars in the frame. However, in eachinstance substantially the same objectionable features exist. It istherefore the purpose and prime object of this invention to provide aheddle-frame having as its characteristic features lightness andrigidity to permit the ready guiding and maintaining of the frames withthe least possible friction as they are reciprocated in operation.

A further object of the invention is to provide a unique device fordetachably securing the heddle-bars in its frame.

Many other objects and advantages will be hereinafter referred to and beparticularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of aheddle-frame and aheddle-bar constructed in accordance with my invention. Fig. 2 is adetail perspective view of one of the end bars and the end of a coactingupper bar. Fig. 3 is a cross-section on the line 3 3 of Fig. 1. Fig. 4is a detail perspective view of a heddle-bar and the means employed forlocking the same in the heddle-frame.

The same numerals refer to like parts in all the figures.

The numerals 1 and 2 indicate upper and lower bars, preferablyconstructed of wood. The bars 1 and 2 are connected at their ends by endbars 3 and 4, formed of channel-iron, the ends 5 and 6 being bent atright angles and embedded in the outer sides of the bars 1 and 2, wherethe respective bars are secured together by any well-known fasteningmeans 7. Hence a complete heddle-frame is constructed providing thenecessary strong and durable, at the same time cheap, wooden bars, whilethe end bars are equally as strong and rigid, yet light and durable.Furthermore, the whole outer surface of the frame is rendered perfectlyflat, presenting an unbroken wearing-surface should the adjacent framesstrike each other while being reciprocated-a condition often experiencedwhen the usual harness is in motion. Moreover, while the frame has thesalient characteristics of lightness and rigidity it is also capable ofbeing easily and conveniently repaired should it become damaged or worn.

The heddle-bars 8 are passed through slots 9 in the end bars 3 and landare held therein by what I shall term a lock-block 10 and a catch 11.Each bar has a slot 12 near one end, in which operates a block 10, whileat the opposite end of each bar is a notch 13, cooperating with thelatch 11. Block 10 consists of an H-shaped piece of metal equal inthickness to the width of the slot 12 of bar 8, said slot beingapproximately the length of the sides 14 of the block. To apply thelockblock, one side 14 is passed through the slot, whereupon it is givena quarter-turn, the connecting section 1 5 of said block being the axis.The block is therefore relatively held against lateral displacement. Bar8 is now passed through the slots 9, the block 10 limiting the movementin one direction, while the notch 13 is engaged by the spring-catch 11,securely holding the heddle-bars against all possible displacement, yetpermitting them to be readily accessible when so desired.

The invention is extremely simple and possesses many decided advantagesover the present state of the art.

While I am aware a metal heddle-frame is old, and distinctly disclaimall claim to such, this structure possessing many of the objectionsheretofore noted; but

What I do claim as new is- 1. A heddle-frame comprising wooden upper andlower bars, and metal channel-irons, connecting said bars, the ends ofsaid wooden bars fitting between the sides of the channelironssubstantially as described.

2. A heddle-frame comprising wooden upper and lower bars, and metalchannel-irons connecting said bars, said channel-irons being bent at theends and secured to the upper and lower bars, the ends of said woodenbars being partially incased by the bent ends of the channel-ironssubstantially as described.

3. A heddle-frame comprising upper and lower wooden bars having theirouter ends and part of their sides adjacent said ends recessed, metalangle-bars formed of channelirons, the ends of said irons being bent,the
